SCHOOL'DESK AND SEAT.

SPECIFICATION forming part of Letters Patent No. 352,762, dated November 16, 1886.

Application filed May 14, 1886. Serial No. 202,181. (No model.) I

To all whom it may concern:

"Be it known that I, JESSE M. LAMB, of Nettle Creek, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in School Desks and Seats; and I do hereby declare the following to be a full, clear, and exact description of the invenart to which it ap'pertains to make and use the same. a

My invention relates to animprovementin In the construction and arrangement of school-desks it is desirable that they should be capable of a ready adjustment both vertically and in a horizontal plane, in order that they may be made to suit the heights of the different scholars, and be arranged to receive the the eyes of the scholars. It is also desirable that the seats should be capable of a vertical pupils, and adapted to swing out of the way when scholars are moving about the room, en tering or returning from the school-room, or going to and from classes. In connection with the above desirable features is another highly important oneviz., that of economy of room.

The object of my present invention is to provide a seat, desk, and back-rest which shall be capable of the seve ral desirable adjustments, and which shall be supported upon a single standard secured to the floor in such a manner as to obstruct it as little as possible.

With these ends in view my invention consists in certain features of. construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, 'Figure 1 is a view of the desk and seat adjusted for use, and Fig. 2 represents the seat turned to one side to admit of passage between the desks.

A represents a hollow or gas-pipe standard, secured in a base, B, which spreads out, preferably in circular form, to receive the screws or bolts 12, which secure it to the floor. v

0n the standard B is sleeved a seat-supporting arm, 0, adapted to slide freely up and down on the standard and to swing to the right and left. The sleeve-arm G is locked atthe desired height on the standard-A by a collar, D,

-rest, 6, for the occupant of the seat 0.

which is located on the standard below the sleeve portion of the arm and provided with a set-screw. d, adapted to impinge against the-.1-

standard and lock the collar thereto. The

position to be occupied, and which tends to hold the seat in its normal adjustment when occupied, but admits of its being readily swung to the right or left by side pressure; or the collar D might be provided with a lug or rib and the seat-supporting arm with a recess.

The seat 0 may be secured to the arm by bolts,

screws, or any well-known or approved means. E represents the desk, to the under side of which is secured the female section F of the complete standard. The standard-section F is also preferably constructed of hollow tub inggas-pipe, for. example and is adapted to fit loosely and slide and rotate within the standard A. It is secured to the bottom of the desk by means of a head, f, similar to the 7 base B, and is locked at the desired height and in the desired rotary adjustment bya setscrew, G, which works in the side Ofthestandard A, and is adapted to impinge against it.

To the back of the deskE is secured a back- The. said back-rest projects above and below the back of the desk, is made transversely concave, andhas a rounded top. It extends quite a distance above and below the desk-back, and

forms an extended rest for the back and shoulders of the scholar occupying the seat, but

does not engage the back in the region of the kidneys,where a pressure is liable to interfere with their action and entail serious quences.

The seat can be elevated or loweredto suit the legs of the scholar occupying it. The desk E, carrying the back e,may be elevated or deconseo pressed to bring the backrest e opposite the 5 portion of the back which it is most desirable to have it engage, and it may be shifted from time to time to prevent the scholar from becoming illyhaped from habitually occupying the same position. These advantages are furthermore supplemented by the compactness of the whole, its many adjustments rendering it perfectly feasible toreverse the sittings of the whole school at short notice or to arrange them at any desired angle to the wall,and the comparatively slight expense at which it may be furnished.

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a standard and a vertically-adj ustable seat secured thereto, of a back-rest adj ustabl y secured to the said stand ard at a point above the seat, substantially as set forth.

2. The combination, with a standard and a seat secured thereto in vertical and laterallyswinging adjustment, of a vertically-adj ustable and laterally-swinging back-rest secured to the standard at a point above seat, substantially as set forth.

3. The combination,with a standard and collar, the latter having a recess therein, and a device for locking the collar to the standard in any tdesired vertical adjustment, of a seat-supporting arm mounted on the standard andprovided with a lug or rib adapted to enter the recess in the collar, substantially as set forth.

4. The combination, with the hollow standand provided with the spreading base and the seat sleeved on the standard in vertical and swinging adj ustment, of the desk secured to a standardsection adapted to fit within thebase standard-section, the back-rest secured to the back of the desk, and the means for locking JESSE M. LAMB.
